The MTG-B3000 features a Dual Core Guard structure, which protects the module in a carbon-reinforced resin case and encloses the exterior in metal components. Repeated pressing, cutting, and polishing builds the stainless steel case back upward into an intricate 3D form. The case back also includes the lugs to secure the band and the guards for crown and buttons, for a completely new structure and a more compact, slimmer timepiece. This watch delivers not just innovative form and sophisticated beauty, but robust functionality, as well. Download the CASIO WATCHES app to pair with your smartphone via Bluetooth®. With Multi Band 6 radio controlled precision, Tough Solar charging, and the high-brightness LED light, this timepiece helps you stay at peak performance, ready for any adventure.
